Installation

The Extron MDA 5SVA RCA, MDA 3AV RCA, and MDA 5AV

RCA are a family of S-video or composite video and stereo audio

mini distribution amplifiers (MDAs) . The stereo audio input and

output are on RCA connectors. Each MDA also has a passive

loop-through for a local monitor.

• MDA 5SVA RCA — S-video DA with one S-video and stereo

audio input and five S-video and stereo audio outputs.

• MDA 3AV RCA — Composite video DA with one video and

stereo audio input and three video and stereo audio outputs.

• MDA 5AV RCA — Composite video DA with one video and

stereo audio input and five video and stereo audio outputs.

The MDAs are rack mountable and have an internal switching

power supply for worldwide power compatibility.

Rack Installation

The 1U high, half rack width MDAs can be mounted on a

standard Universal 1U Rack Shelf (Extron part #60-190-01) (figure

1). If desired, mount the MDA as follows:

(2) 4-40 x 3/16" Screws

Use 2 mounting holes on

opposite corners.

False front panel

uses 2 front holes.

screws in opposite (diagonal) corners to secure the MDA to

the shelf.

3. Install the blank panel (included with the rack shelf) or

another half-rack unit to the rack shelf.

4. Insert the shelf into the rack, aligning the holes in the shelf

with those of the rack.

5. Secure the shelf to the rack using the supplied machine

screws.
